The following example uses a simple for..in loop to iterate over each of the properties in the onCuePoint callback handler's infoObject parameter and trace a message when cue point data is received:

var nc:NetConnection = new NetConnection();
nc.connect(null);

var ns:NetStream = new NetStream(nc);
ns.client = this;
ns.play("video.flv");

var vid:Video = new Video();
vid.attachNetStream(ns);
addChild(vid);

function onCuePoint(infoObject:Object):void
{
    var key:String;
    for (key in infoObject)
    {
        trace(key + ": " + infoObject[key]);
    }
}

The following output appears:

parameters: 
name: point1
time: 0.418
type: navigation

This code used one of several techniques to set the object on which the callback method was invoked. You can use other techniques; for more information, see Writing callback methods for onCuePoint and onMetaData.
